8 Claims.

This invention relates to improvements in mops and especially to that type of mops which are adapted for the polishing of floors and the like and which are provided with means for carrying on the head thereof a quantity of cleaning fluid and to distribute the same over the mop material.

It is the object of this invention to provide i1. proved means for attaching the mop fabric to the mop head and to hold it securely in place thereon.

t is another object of the present invention to secure the mop fabric on the mop head in a positive manner that it can neither slide longitudinally nor transversely thereon and yet may be quickly removed therefrom.

It is another object of this invention to provide a mop of this type in which the mop material when in use completely shields objects which might be injured from contact with the metal parts of the mop. I

With these and other objects in view the invention consists in certain novel combinations and arrangements of parts hereinafter more clearly described and finally pointed out in the appended claims and illustrated in the accompanying drawing in which:

Fig. 1 is a plan View of the improved mo head.

Fig. 2 is a side elevation of the mop shown in Fig. 1.

Fig. 3 is a plan view of the mop base or plat 10 when separated from the mop head.

Fig. 4 is a sectional elevation of plate 10 on line 4-4 of Fig. 3.

Fig. 5 is a plan of the looped frame 20 with the mop fabric thereon when separated from the plate 10.

Fig. 6 is a sectional elevation of a part of the mop head on line 6-6 of Fig. 1.

Referring to the drawing 10 represents a flat plate preferably stamped from sheet metal and of heart or similar shape as shown in Fig. 3. This plate forms the body portion of the mop head and is provided on its peripheral edge with a plurality of pointed teeth or prongs 11 spaced from each other, which extend outwardly therefrom in the plane of plate 10. The upper surface of plate 10 is formed with an indented groove 12 which surrounds the major part thereof near the periphery of the plate. his indentation is adapted to contain cleaning fluid or polishing oil and to distribute it upon the mop material below plate 10 through the apertures in groove 12. Any overflow of oil will be absorbed directly by the mop material surrounding plate 10. Within the groove 12 are a plurality of small perforations 13 which extend through the material of plate 10.

Referring to Fig. 5, 20 represents a looped frame preferably made from a resilient metallic strap or spring bent into heart or similar shape to surround the plate 10. The end portions 21 of strap 20 are bent towards tie interior of the loop formed by said strap and in upward direction to lie above the plane of the loop portion of the 2) are provided with apertures 22 along the longitudinal center line of strap 20. ihe loop portion of strap 20 has a plurality of apertures 23 transversely therethrough which are spaced from each other to conform The mop material 30 is preferably formed by a plurality of cords forming a layer to the middle portion of which is sewed longitudinally on both sides a strip of fabric 31 or binder to join the cords together. This layer of mop material is then folded at the longitudinal center of the fabric-covered portion and sewed together along the edges of the fabric so that a fabric-covered tube 31 is formed from which the mop cords 30 protrude. This tube 31 is threaded upon the looped metal strap 20 as shown in Fig. 5 so that only the inwardly bent end portions 21 thereof remain uncovered.

The plate 10 is placed within the loop portion of the expanded frame formed by the strap 20 so that the teeth 11 on plate 10 come opposite apertures 23 of strap 20.

A handle connector having a tubular portion preferably stamped from sheet metal is provided with apertured lugs 41 at its upper end which maybe pressed against each other by means of a screw 42 and nut 44 to clamp a handle 42 within the connector. The lower end of the tubular holder is collapsed to form parallel plates 45 which are adapted to fit between the end portions 21 of strap 20. They are fastened thereto by means of screw 46 which is accommodated in apertures 22 and wing nut 47 on said screw.

After the connector 40 is placed between the ends 21 in the above described manner these ends are gradually tied together and pressed towards plates 45 of the connector 40. The whole frame 20 is thus contracted and the teeth 11 on plate 10 are pressed into the inward fabric of tube 31 and through this enter into apertures 23 of strap 20, forming thereby a rigid connection of the looped frame with plate 10 and hold the mop fabric against any displacement or slipping on its support.

with the spacing and places of teeth 11 on plate From the foregoing it will be clear that this improved mop consists of only four principal elements namely the plate 10, the frame 20, the mop material 3031 and the connector 40. All these elements are of a most simple form and joined to each other by operation of the single screw 46 with nut 47. Nevertheless this mop has all the advantages, performs all the functions and is of equal rigidity and greater convenience in operation than mops of this type which are now in use, but embodies less and simpler parts and therefore can be made and sold at a very reasonable price.

Having thus described the preferred form of my improved oil mop, it is to be understood that changes may be made in the arrangement of its parts and construction of minor details thereof as come within the scope of the invention as claimed, without departing from the spirit of the invention.

I claim:

1. In a mop, a head including a body portion confined to a single plane, a resilient spring in loop formation surrounding the periphery of said body portion and having inwardly turned free ends spaced from each other adapted to hold a handle therebetween, mopping material detachably mounted on the loop portion of said spring, a handle between said free ends and common means for pivotally and detachably fastening said 1 handle to the spring and for detachably clamping the spring and mopping material thereon against the body portion.

2. In a mop, a head consisting of a flat plate forming a body portion in a single plane, a resilient looped spring surrounding the periphery of said body portion, the free ends of said spring extending inwardly of said loop, mopping material detachably mounted on said resilient spring, prongs formed on said body portion adapted to impinge the mopping material and to press against said spring, a handle between the free ends of said spring, and common means passing through said free ends, pressing them against said handle for pivotally and detachably fastening the handle to the spring and for contracting the loop of said spring to bind the spring and mopping material to the body portion.

3. In a mop, a head including a flat body portion, a resilient looped spring surrounding the periphery of said body portion, having spaced apertures and free ends extending parallel to each other, mopping material detachably mounted on said spring, prongs formed on said body portion and adapted to impinge said mopping material and to protrude into the apertures in said spring, a handle between said parallel ends, and common means pressing said free ends against said handle for pivotally and detachably fastening the handle to the spring and for contracting the loop of the spring to bind the spring and mopping material to the body portion.

4. In a mop a flat body portion, a resilient spring in loop formation surrounding the periphery of said body portion and having inwardly turned free ends spaced from each other, mopping material carried by said spring, a handle between the free ends and a nut and screw connection between the handle and free ends whereby setting up on the nut tends to bind the spring and mopping material to the body portion.

5. In a mop, a mop head including a flat metallic body portion, having prongs formed on its periphery, a resilient metallic strap in looped formation surrounding the periphery of said body portion, said strap having spaced apertures and terminating in inwardly turned free ends spaced from each other, mopping material having a tubular binder mounted on said strap, said prongs being positioned in alignment with said apertures and adapted to pass through said binder into said apertures, a handle having its lower end positioned between said free ends of the spring and a nut and screw connection between the lower end of the handle and the free ends whereby pressure exerted on said nut fastens the spring and mopping material. to the body portion.

6. A mop head comprising a looped frame consisting of a resilient metallic strap having its ends directed toward the interior of the loop formed thereby and laterally inclined with respect to the plane of said loop, clamping means engaging said ends to contract said loop, a tubular mop fabric covering the looped portion of said strap, a flat metallic plate within the loop of said frame and projections on the periphery of said plate impinging upon the inner face of said tubular mop fabric when said frame is contracted.

7. In a mop head a resilient fiat metallic strap forming a loop, spaced recesses in the inner face thereof, the ends of said strap being inwardly and laterally bent with reference to the plane of said loop, tying means adapted to contract said loop passing transversely through said ends and holding a handle connector rotatably therebetween, a tubular mop fabric covering the looped portion of said strap, a flat metallic plate within said loop having spaced projections on its periphery engaging said mop fabric and the recesses in said strap when the strap is tied against said handle connector.

8. In a mop a head including a fiat body portion a resilient strap detachably held on said body portion forming a flange therearound providing means to confine oil on said body portion, means for fastening said strap and body portion together and mop material compressed in the joint between said strap and body portion.
